Victoria Day Holiday (celebrating the late Queen Victoria) - usually referring to the whole long weekend since Victoria Day is always the third Monday in May. Many people like to drink during this weekend, and since Canadians often buy beer in cases of twenty-four, it's called a two-four for short. Also, the holiday itself usually falls around the 24th of May.

May 24 was queen victoria's birthday.

I've lived on Vancouver Island, about
10km from Merville for 25 years, and I
have never once heard this term. Comment by: Tyler Rated:1/5

This slang is in reference to the well
known
fashion faux pas of the Melville
Islander. All
Canadians know NOT to use this term in
front of the locals - it would be like
using
the N word at a Chicken and Waffle
shack. Comment by: A True Canadian Rated:4/5
